golang convert Chinese characters to pinyin

With the rise of social networks and search engines, people increasingly rely on text input and processing in their daily lives. Pinyin strings are a common way of converting Chinese characters into audio. It helps improve the accuracy of text editing and searching. This article will introduce how to use Golang to write a program that converts Chinese characters into Pinyin strings.

1. Preparation

Before writing the program, we need to install the github.com/mozillazg/go-pinyin module. You can install it by running the following command:

go get github.com/mozillazg/go-pinyin

This library provides a convenient API that can convert Chinese characters into their corresponding pinyin. In this example, we will use the API to convert Chinese characters to Pinyin.

2. Create a program

Next, we will start writing a program that converts Chinese characters into pinyin strings. The following is a sample program that takes a string of Chinese characters and converts it into the corresponding pinyin string.

package main

import (
    "fmt"

    "github.com/mozillazg/go-pinyin"
)

func main() {
    hans := "中国"
    fmt.Println(pinyin.Convert(hans, nil))
}

In the above code, we imported the go-pinyin library and used the Convert() method to convert the string "China" to a pinyin string . The result is:

[zhōng guó]

The above code also provides an optional "Option" parameter, which is used to specify the conversion method during conversion. For example, if you want to convert "中国" into its numeric pinyin, run the following code:

package main

import (
    "fmt"

    "github.com/mozillazg/go-pinyin"
)

func main() {
    hans := "中国"
    convertor := pinyin.NewArgs()
    convertor.Style = pinyin.Tone2
    fmt.Println(pinyin.Convert(hans, convertor))
}

In the above code, we specified the pinyin.Tone2 option to convert "中国" Pinyin string converted into numeric form. The result is:

[zhong1 guo2]

3. A complete program for converting Chinese characters to Pinyin

Now, we can write a complete program for converting Chinese characters to Pinyin based on the above example program. The following is a complete program:

package main

import (
    "fmt"
    "strings"

    "github.com/mozillazg/go-pinyin"
)

func main() {
    str := "前途未卜"
    convertor := pinyin.NewArgs()
    convertor.Style = pinyin.Tone
    pinyinStr := make([]string, 0)
    for _, r := range str {
        pyArr := pinyin.Pinyin(string(r), convertor)
        if len(pyArr) > 0 {
            pinyinStr = append(pinyinStr, pyArr[0])
        } else {
            pinyinStr = append(pinyinStr, string(r))
        }
    }
    fmt.Println(strings.Join(pinyinStr, " "))
}

In the above code, we use a loop to process the input string, convert it character by character into the corresponding Pinyin string, and store it into a character in string array. Finally, we use the Join() function to join all the strings into one string.

To run the above program, please execute the following command:

$ go run main.go

The result should be:

qián tú wèi bǔ

IV. Summary

In this article, we use Use the github.com/mozillazg/go-pinyin library to write a simple program for converting Chinese characters into pinyin strings. In addition, we also introduced how to use this library to convert Chinese characters into a specific pinyin format. Using these techniques, you can add support for Chinese input to your program and improve its text search and editing accuracy.
